Greenhouse gas-monitoring aircraft keep tabs on the Amazon's rising methane levels

Research led by the National Centre of Earth Observation at the University of Leicester is going to new heights in the atmosphere to get a better handle on methane emitted from wetlands in the Amazon. Using small aircraft flying in an upward spiral and collecting samples of the air, t

Arctic sea ice heading towards second lowest on record

This year the extent of summer sea ice in the Arctic is heading towards being the second lowest on record. The Arctic sea ice minimum marks the day – typically in mid-September – when sea ice reaches its smallest extent at the end of the summer melt season. British Antarctic Survey se

Free-swimming Ocean Gliders Help Scientists Understand Storm Intensity

A regional team from Woods Hole Oceanographic Institution (WHOI), Rutgers University, the University of Maine, the University of Maryland, and the Gulf of Maine Research Institute mobilized Friday in advance of post-Tropical Storm Hermine’s arrival in the Northeast to gather data from

Calculating the role of lakes in global warming

As global temperatures rise, how will lake ecosystems respond? As they warm, will lakes — which make up only 3 percent of the landscape, but bury more carbon than the world’s oceans combined — release more of the greenhouse gases carbon dioxide and methane? And might

Increased ocean acidification is due to human activities, say scientists

Oceanographers from MIT and Woods Hole Oceanographic Institution report that the northeast Pacific Ocean has absorbed an increasing amount of anthropogenic carbon dioxide over the last decade, at a rate that mirrors the increase of carbon dioxide emissions pumped into the atmosphere.

Tropics told to ban coral-killing sunscreen

Tropical island nations should team up to ban coral-killing sunscreen products, following the example of Hawaii, a conference has heard. Chemical compounds in sunscreen lotions cause irreparable damage to reefs, which are crucial to the livelihoods of 500 million people in the tropics

Future fisheries can expect $10 billion revenue loss due to climate change

Global fisheries stand to lose approximately $10 billion of their annual revenue by 2050 if climate change continues unchecked, and countries that are most dependent on fisheries for food will be the hardest hit, finds new UBC research. Climate change impacts such as rising temperatur

Toxic air pollution nanoparticles discovered in the human brain

A team involving Oxford University scientists has, for the first time, discovered tiny magnetic particles from air pollution lodged in human brains – and researchers think they could be a possible cause of Alzheimer’s disease. Researchers led by Lancaster University found abunda

Subantarctic seabed creatures shed new light on past climate

A new marine biodiversity study in one of the largest Marine Protected Areas in the world reveals the impact of environmental change on subantarctic seabed animals and answers big questions about the extent of South Georgia’s ice sheet during the Last Glacial Maximum around 20,0

Clues in ancient mud hold answers to climate change

New research suggests that Africa has gradually become wetter over the past 1.3 million years — instead of drier as was thought previously. The research from Berke, assistant professor in the Department of Civil and Environmental Engineering and Earth Sciences at the University
